What are alleles and how do they relate to genes?

Question 3 options:

Alleles are segments of DNA that contain instructions for building and maintaining an organism. They determine our traits.

Alleles are tools used by scientists to study the inheritance of traits and perform dihybrid crosses.

Alleles are concepts in non-Mendelian genetics that explain how traits are inherited.

Alleles are different versions of genes that determine our traits, such as eye color and hair texture.

Alleles are different versions of genes that determine our traits, such as eye color and hair texture. They are alternative forms of a gene that arise by mutation and are found at the same position on a specific chromosome. Alleles can be dominant or recessive, meaning that one allele may mask the effects of another allele. They relate to genes as they are specific variations of a gene that contribute to the overall genetic makeup of an individual.
